I changed the battery in all my smoke detectors and one of the detectors (serial # SC9120B) continues to beep. I've tried numerous brand new batteries in the detector and nothing changes. I've also tried unplugging it and plugging it back in with no let up of the beeping. It's driving us crazy!! What do you suggest I do next?
